. if we want the composition to be topmost played. The exterior and interior design of the vehicle was a special challenge as I wanted to achieve an attractive apperance that radiates youth and sportivitiy and isn’t just a style experiment. Tako smo dosegli enostavno konstrukcijo z razmeroma veliko vzvojno togostjo glede na tip vozila. neizmerno veliko izkušenj na področju konstruiranja. I wanted a vehicle to be recognizable by few original and unique lines that would mark the whole form and unite all of the elements in a harmonic totality. This way a simple design with relatively high torsional stiffness was accomplished in comparison with the vehicles of the same type. ki je koncipirana kot »space-frame« iz treh glavnih modulov: sprednjega dela. ki je na koncu pripeljal do izdelka. Oblika vozila je bila poseben izziv.

Avtomobil je bil koncipiran od znotraj navzven: okoli mehanskih sklopov je bila na novo narejena ergonomija kabine. Prepričan sem. Projekt je povezal akademsko sfero z industrijo in dal vsem. Na njem se je urilo skoraj 40 študentov. saj sem želel doseči atraktivno obliko. ki bi zaznamovale celotno obliko in vse elemente združile v usklajeno celoto. In this project almost 40 students were trained with “case-study” methods and are now ready to take the chalanges waitng for them in the industry. ki so drzni. da je skladba vrhunsko odigrana. around it and supporting structure and after that the exterior and interior design. Povsem na novo je zasnovana nosilna konstrukcija. activities on High school of Mechanical Engineering and a lot of other executants was a big organizational challenge which was in the end demonstrated by a product which we’re all proud of. the cabin and the rear part. Each one of us who has actively participated in this project has realized that in order to have a successfull project we have to work as well-trained orchestra where all of the instruments are mutually harmonized and carefully directed. smo spoznali. not afraid of challenges and are working as homogeneous whole in order to achieve common goals. da moramo za uspešen projekt delovati kot dobro uigran orkester. kjer so vsi inštrumenti med seboj usklajeni. The greater part of mechanical components and electronic are taken from Peugeot 406. na katerega smo vsi ponosni. Želel sem si. Organizacija in usklajevanje aktivnosti vseh članov skupine. The supporting frame is completely newly designed and is projected as “space-frame” of three main modules: the front part. če želimo. nato pa še oblika. development evaluations and making prototypes to all who worked on it. The project connected an academic sphere with industry and gave immense experience in the sphere of constructing. aktivnosti na Srednji strojni šoli ter veliko drugih podizvajalcev sta bila kar velik izziv.

On the construction and analysis of the safety belt fastenings
I worked on the construction and analysis of the safety belt fastenings. as well as carrying out an analysis of the front bumper. je njegove varnostne lastnosti mogoče pokazati samo z numerično simulacijo. With help of linear and non-linear numerical analysis in the diploma for every fastening made. Najprimernejša konstrukcija je bila nato tudi dejansko izvedena. I am very proud to be a part of this project and that what I contributed to the realization of this car will crucially contribute to the improved safety of the passengers.
One of the most demanding analyses was the analysis of a collision to the front part of the car. realize new ideas. solve real problems and improve existing solutions. From a technical point of view. sama oblika pa mora biti funkcionalna in ergonomična. Ker je vozilo Student Roadster prototip. gain new knowledge through work. safety is one of more important characteristics of a vehicle. all of this is invaluable experience for everybody on the project.
Za zagotovitev skladnosti z zakonodajo so bili izvedeni številni preračuni. we improved the individual fastenings. crash testom. d. Površine morajo imeti privlačne oblike. prekrite morajo biti s prijetnim materialom. i. tudi analiza priključkov varnostnih pasov.
Ena najzahtevnejših analiz je bila analiza trka sprednjega dela avtomobila. it is important that it is pleasing.
Ukvarjal sem se s konstrukcijo in analizo pritrdišč varnostnih pasov. Priučeno teorijo izkusiti v praksi. crash test)
On constructing the interior and the numerical simulations of the crash test
As the interior of the vehicle is the part that every user has the most contact with. to ensure accordance with legislation. including an analysis of seat-belt connections. i. uresničiti nove zamisli. ki je izvedla tudi analizo sprednjega odbijača. reševati resnične probleme in izboljševati obstoječe rešitve je neprecenljiva izkušnja za vsakega. Vrednotenje teh vitalnih elementov je v svoji diplomski nalogi izvedel Robert Povšič. The crash test is also important as a certificate of the adequacy of a vehicle by homologation. Varnostne pasove je bilo treba umestiti v potniško kabino v skladu z veljavno zakonodajo.
Ker je notranjost avtomobila tista. Projekt Student Roadster nam je omogočil prav to. its safety performances can only be shown through numerical simulation. Ponosen sem na to. je pomembno. To use theoretical experience in practice. ki bo odločilno pripomogel k večji varnosti potnikov.

I would like to thank to all members of the current team for accepting me and by doing so making the 5th year of my studies of mechanical engineering more entertaining. ko sem skupaj s sošolci opravljal enomesečno prakso v laboratoriju LAVEK. when I and my schoolmates were on our one-month practice in the LAVEK laboratory.

. saj sem izvedel veliko novega in zanimivega. Za projekt sem se bolj resno začel zanimati lani. ekipi pa sem se nato pridružil oktobra. when the vehicle was to be prepared for the conference IAT 07 and I joined the team in October. The painting of the car was done in a chamber by a professional lacquerer. V veliko veselje mi je bilo delati v tem projektu.36

O delu v projektu
Za projekt Student Roadster sem izvedel konec drugega letnika. da bo avto sploh kdaj izdelan.
Barvanje avtomobila je potekalo v komori s profesionalnim ličarjem. sem pa pomagal pri izdelavi karoserije in montaži posameznih delov. At that time I could not imagine that the vehicle will ever be made.

Due to the method of production of the exterior of the vehicle and a wide range of used materials. o. I think that all who have worked on this design project have earned praise. Žiga Zadnik. High and low beams. we get the answer to the ever present question “why”. the integrated hinges and closing mechanism are taken from Peugeot 406 and with smaller adjustments they function very well. saj so odlično opravili tudi svoje delo. priskočil na pomoč.
Skupinska slika najdejavnejših članov projektne skupine. V sprednji žaromet so integrirani dolgi in kratki pramen. o. ko sem ga potreboval. ko se usedem v malo bolj eksotičen avto in se z njim poženem po skoraj prazni cesti. the product is technically a very good solution. Zaradi načina izdelave zunanjosti vozila in širokega nabora uporabljenih materialov je bila. Because of a relatively simple final design of opening the Student Roadster’s lid. zahtevna naloga izdelava in pritrditev notranjih oblog iz tkanine.
On the development and design of headlamps
I have always been a passionate admirer of cars. where they were also made. pozicijska luč ter smerokaz. Splošno je znano. Menim. je neizbežna. Because of fuel in the blood and the joy of driving on asphalt. saj gre za moje vsakodnevno delo.. A group photo of the most active members of the project team who completed the car. Konstruiral jih je Donald Abrič Pleterski v sodelovanju z našim partnerjem podjetjem Hella Lux Slovenija. Aleš Gosar. as they have done their job perfectly. o. close and lock. Ana Bižal. ki štejejo.

O izdelavi prtljažnega prostora About designing the boot
Every element of the vehicle must perform its function as well as possible – that goes also for the boot. da je izdelek tehnično zelo dobra rešitev. če bi bilo na voljo vsaj še nekaj časa. Uroš Rosa. For these reasons. who has offered help at every moment when I needed him. The boot lid has to open. ki so avto izdelali do konca. Delo se je odvijalo v sinergiji z vodjo projekta in stilistom Urošem Roso. Od leve proti desni: Andrej Škrlec. It is well known that the difference between the theory and the practice is immense. zanimivo. ki je tudi sponzoriralo projekt z izdelavo sprednjih žarometov in nabavo svetlobne opreme za zadnji del avtomobila. The craziest and most simple ideas are those that count and in the end everything depends on the most important attribute of the best engineers – the team work. that’s why I feel great when I sit in a more exotic car and drive down an “almost” empty road. razvoj in izdelavo pa sem izpeljal s sodelavci v podjetju. d. avto pa je videti odlično. Vsi. Žarometi so se zelo dobro zlili s karoserijo.

. ki mi je vsak trenutek. po možnosti čim bolje – tako je tudi s prtljažnikom. Aleš Gosar.o. da so malenkosti tiste.. Zaradi goriva v krvi in veselja do vožnje po asfaltu sem se odločil za delo v avtomobilski industriji in se zaposlil v oddelku za razvoj svetlobne opreme v podjetju Hella Lux Slovenija. David Volk in Tomaž Kovšca. but only by participation in such an extensive project as Student Roadster. stisk roke in odlično službo.

Vsak element vozila mora opravljati svojo funkcijo. the making and fastening of interior linings was a very exacting task.. The revelation that little things are those which give a mark to the day is inevitable. They were designed by Donald Abrič Pleterski in cooperation with our partner Hella Lux Slovenija d. From the left: Andrej Škrlec. zapirati in zakleniti. David Volk and Tomaž Kovšca. Tudi zato je bil moj prispevek k projektu Student Roadster več kot primeren in enostaven. razviti in izdelati žaromete za roadsterja. Najbolj nore in najbolj preproste zamisli so tiste. ki ga sicer v razvoju vedno manjka. which could be improved with further development if there was “some more time” – which is always lacking in development. Uroš Milost. develop and design the headlamps for the roadster. o. the headlamps suit the car-body and the car looks superb. zaslužijo pohvalo. my contribution to the Student Roadster project was more than basic as I perform this work every day. My task was to plan. Uroš Rosa. Uroš Milost. who also sponsors the project on the making of the front headlamps and the supply of light equipment for rear part of the car.. pa pride odgovor na tisti večni zakaj. šele s sodelovanjem pri tako obsežnem projektu. Pokrov prtljažnega prostora se mora odpirati.o. The style plan was made by Uroš and me together and the development and design was performed by me and my co-workers in the enterprise. position lamp and indicator are integrated in the headlamp.Donald Abrič Pleterski

O razvoju in izdelavi žarometov
Že od nekdaj sem strasten ljubitelj avtomobilov. a handshake and a perfect job. Ugotovitev. d. ki z manjšimi predelavami tudi tu dobro opravljajo svoje delo. Moja naloga je bila zasnovati. kjer so jih tudi izdelali. In my opinion. zato se odlično počutim. kot je Student Roadster. Work was performed in synergy with the manager of the project and the stylist Uroš Rosa. Otherwise.

Sprednji žarometi so eden od najzanimivejših delov avtomobila. ki so sodelovali pri izdelavi. Ana Bižal. o. Zaradi razmeroma enostavne končne izvedbe odpiranja pokrova Student Roadsterja so vanj vgrajeni tečaji in zapiralni mehanizem prtljažnika peugeota 406. Žiga Zadnik. ki bi jo z nadaljnjim razvojem lahko še izboljšali. Headlamps are one of the most attractive parts of the vehicle. ki dajo dnevu predznak. d. da znajo biti razhajanja med teorijo in prakso velika. Stilsko zasnovo sva naredila z Urošem skupaj. I started to work in the car industry and got a job in the department for the development of light equipment in the enterprise Hella Lux Slovenija ltd. o. na koncu pa je vse odvisno od najpomembnejše odlike najboljših inženirjev – timskega dela.

and the window itself. the opening-closing mechanism and the window moving mechanism. We believe we have finished this project successfully. zapiralno-odpiralni mehanizem in mehanizem za pomik stekla. saj smo študentje s tem projektom spoznali. We have faced different problems. kaj pomeni prenesti teoretična znanja in modele v prakso. kot je Student Roadster.Aleš Gosar in Bojan Tomić
Konstrukcija in izdelava vrat
Vrata niso videti kompleksen sistem. Soočala sva se z različnimi problemi. which is a key competence of any good engineer. Positioning the door hinges took us quite some time. na Fakulteti za strojništvo primanjkuje. saj je bilo treba zagotoviti ustrezno odpiranje vrat. vendar se zavedava. and would not be too big for the door. Najti je bilo namreč treba steklo.
Design and making of the doors
Student Roadster
The door does not seem as a complex system. pri čemer se vrata ne smejo zajedati v bok vozila. the biggest being the lack of space and the window moving mechanism. vendar pa so v njih osnovna nosilna konstrukcija vrat. ki bi po obliki ustrezalo loku sprednjega stebrička in celotnemu dizajnu ter ne bilo preveliko za naša vrata. This project helped students realise how to turn theoretical knowledge and models into practice. but at the same time we are aware that everything can be done even better. Projektov. There is not enough projects like Student Roadster at the Faculty of Mechanical Engineering. Veliko časa nama je vzelo tudi pozicioniranje tečajev vrat. kar pa je ključno znanje vsakega dobrega inženirja. We had to find a window that would fit the curve of the front column as well as correspond to the entire design. da je vsako stvar mogoče narediti še bolje. We had to ensure that the door would open properly and would not collide with the side of the vehicle. da sva projekt opravila zelo uspešno. Meniva. največji pa sta bila prostorska stiska in mehanizem za pomik stekla oziroma steklo samo.
